Description

本発明は、薬液を供給するための薬液供給器具に関する。 The present invention relates to a chemical solution supply device for supplying a chemical solution.

従来、皮膚等の被供給部に薬液を供給するための薬液供給器具が知られている。例えば、特許文献１には、薬液を収容する容器と、容器に接続された栓体と、栓体に接続された内蓋と、スポンジと、を備える薬液塗布器具が開示されている。栓体は、容器の口部に接続（圧入）されている。内蓋には、薬液の流出口が形成されている。内蓋のうち前記流出口を取り囲む流出部は、容器の内部から外部に向かうにしたがって次第に前記流出口が小さくなるように傾斜する形状に形成されている。また、栓体には、スプリング及び可動弁が接続されている。スプリングは、内蓋の内側から内蓋に向かって可動弁を付勢する。可動弁は、前記流出部に面接触する形状を有する肩部と、肩部から容器の外側に向かって突出する突起部と、を有している。突起部の外形は、前記流出口よりも小さく設定されており、突起部は、内蓋の外面よりも外部に突出する形状を有している。スポンジの外縁は、内蓋の外縁に固定されている。スポンジは、内側から外側に向かって突起部に付勢されることによって外向きに凸となるように膨出する形状に維持されている。 Conventionally, a drug solution supply device for supplying a drug solution to a supplied portion such as skin has been known. For example, Patent Document 1 discloses a chemical solution application device including a container for containing a chemical solution, a plug body connected to the container, an inner lid connected to the plug body, and a sponge. The stopper is connected (press-fitted) to the mouth of the container. An outlet for the drug solution is formed on the inner lid. The outflow portion of the inner lid that surrounds the outflow port is formed in a shape that is inclined so that the outflow port gradually becomes smaller from the inside of the container toward the outside. Further, a spring and a movable valve are connected to the plug body. The spring urges the movable valve from the inside of the inner lid toward the inner lid. The movable valve has a shoulder portion having a shape of surface contact with the outflow portion, and a protrusion portion protruding from the shoulder portion toward the outside of the container. The outer shape of the protrusion is set smaller than the outlet, and the protrusion has a shape that protrudes outward from the outer surface of the inner lid. The outer edge of the sponge is fixed to the outer edge of the inner lid. The sponge is maintained in a shape that bulges outward by being urged by the protrusions from the inside to the outside.

この薬液塗布器具を用いた薬液の皮膚への塗布は、例えば以下のようにして行われる。まず、スポンジの外面が下を向く姿勢で当該外面を皮膚に押し付ける。このとき、突起部がスプリングの付勢力に抗して内蓋の内側に向かって押圧されることによって流出部と肩部との間に隙間が形成されるので、流出口を通じて容器内の薬液が内蓋外に流出する。この薬液は、スポンジに含浸する。その後、薬液塗布器具をそのまま皮膚に沿って側方に移動させる。これにより、スポンジに保持された薬液が皮膚に塗布される。 The application of the chemical solution to the skin using this chemical solution application device is performed, for example, as follows. First, the outer surface of the sponge is pressed against the skin with the outer surface facing downward. At this time, the protrusion is pressed toward the inside of the inner lid against the urging force of the spring, so that a gap is formed between the outflow portion and the shoulder portion, so that the chemical solution in the container can be discharged through the outlet. It flows out of the inner lid. This chemical is impregnated into a sponge. After that, the chemical application device is moved laterally along the skin as it is. As a result, the chemical solution held on the sponge is applied to the skin.

特許文献１に記載されるような薬液供給器具では、被供給部（皮膚等）の汚れがスポンジに付着することによって当該スポンジに目詰まりが生じ、薬液の供給量が不足するおそれがある。 In a chemical solution supply device as described in Patent Document 1, dirt on the supplied portion (skin, etc.) adheres to the sponge, which may cause clogging of the sponge, resulting in a shortage of the chemical solution supply amount.

そこで、スポンジを使用しないこと（取り除くこと）が考えられる。しかしながら、単純にスポンジが取り除かれた場合、薬液の供給量が過剰となる。具体的に、スポンジは、薬液を含浸させる（保持する）機能と被供給部（皮膚等）にほぼ定量の薬液を供給する機能とを有するため、そのスポンジが取り除かれると、流出口を通じて流出した薬液の全量が一気に被供給部に供給されることになる。このことは、可動弁の押圧量が増えるほど顕著になる。 Therefore, it is conceivable not to use (remove) the sponge. However, if the sponge is simply removed, the amount of the chemical solution supplied becomes excessive. Specifically, since the sponge has a function of impregnating (holding) the chemical solution and a function of supplying a substantially fixed amount of the chemical solution to the supplied portion (skin, etc.), when the sponge is removed, the sponge flows out through the outlet. The entire amount of the chemical solution will be supplied to the supplied part at once. This becomes more remarkable as the pressing amount of the movable valve increases.

（第１実施形態）
本発明の第１実施形態の薬液供給器具１について、図１〜図８を参照しながら説明する。(First Embodiment)
The drug solution supply device 1 of the first embodiment of the present invention will be described with reference to FIGS. 1 to 8.

図１に示されるように、本薬液供給器具１は、容器１０と、薬液供給具２０と、キャップ７０と、を備えている。 As shown in FIG. 1, the drug solution supply device 1 includes a container 10, a drug solution supply tool 20, and a cap 70.

容器１０は、薬液（図示略）を収容する収容部１２と、収容部１２に接続された口部１４と、を有する。口部１４は、特定方向（図１の上下方向）に開口する形状を有する。口部１４の外周面には、雄ねじ部１５が形成されている。 The container 10 has an accommodating portion 12 for accommodating a chemical solution (not shown) and a mouth portion 14 connected to the accommodating portion 12. The mouth portion 14 has a shape that opens in a specific direction (vertical direction in FIG. 1). A male screw portion 15 is formed on the outer peripheral surface of the mouth portion 14.

薬液供給具２０は、口部１４に接続された状態において容器１０内が密閉された状態と収容部１２内の薬液を容器１０外に供給可能な状態とを切り替え可能なユニットである。具体的に、薬液供給具２０は、口部１４に接続可能な基体３０と、基体３０に保持された供給体５０と、を有する。 The chemical solution supply tool 20 is a unit capable of switching between a state in which the inside of the container 10 is sealed and a state in which the chemical solution in the storage portion 12 can be supplied to the outside of the container 10 in a state of being connected to the mouth portion 14. Specifically, the chemical solution feeder 20 has a base 30 that can be connected to the mouth portion 14 and a feeder 50 that is held by the base 30.

基体３０は、口部１４に接続された状態で容器１０内と容器１０外とを連通させる形状を有する。基体３０は、被接続部３２と、規制部３４と、抜止部４０と、押付部４２と、を有している。本実施形態では、被接続部３２、規制部３４、抜止部４０及び押付部４２は、一体成形されている。ただし、これらは別部材で形成されてもよい。 The substrate 30 has a shape that allows the inside of the container 10 and the outside of the container 10 to communicate with each other while being connected to the mouth portion 14. The substrate 30 has a connected portion 32, a regulating portion 34, a retaining portion 40, and a pressing portion 42. In the present embodiment, the connected portion 32, the regulating portion 34, the retaining portion 40, and the pressing portion 42 are integrally molded. However, these may be formed of separate members.

被接続部３２は、円筒状である。被接続部３２の外径は、口部１４の内径よりもわずかに小さく設定されている。 The connected portion 32 has a cylindrical shape. The outer diameter of the connected portion 32 is set to be slightly smaller than the inner diameter of the mouth portion 14.

抜止部４０は、被接続部３２が口部１４に接続（圧入）されたときの容器１０の外側に位置している。抜止部４０は、基体３０からの供給体５０の離脱を阻止するように口部１４を基準として収容部１２と反対側（図１では上側）から供給体５０に接触する。具体的に、抜止部４０は、被接続部３２の中心軸Ｃを中心とする周方向の全域にわたって供給体５０に接触する形状を有する。 The retaining portion 40 is located on the outside of the container 10 when the connected portion 32 is connected (press-fitted) to the mouth portion 14. The retaining portion 40 comes into contact with the feeder 50 from the side opposite to the accommodating portion 12 (upper side in FIG. 1) with reference to the mouth portion 14 so as to prevent the feeder 50 from detaching from the substrate 30. Specifically, the retaining portion 40 has a shape that contacts the feeder 50 over the entire area in the circumferential direction centered on the central axis C of the connected portion 32.

押付部４２は、被接続部３２の内側に接続されており、供給体５０を抜止部４０に向けて押し付ける。押付部４２は、供給体５０を保持する保持部４４と、保持部４４を容器１０の外側に向けて付勢する付勢部４６と、を有する。 The pressing portion 42 is connected to the inside of the connected portion 32, and presses the feeder 50 toward the retaining portion 40. The pressing portion 42 has a holding portion 44 for holding the feeder 50, and an urging portion 46 for urging the holding portion 44 toward the outside of the container 10.

保持部４４は、供給体５０を保持した状態で被接続部３２の内側において前記中心軸Ｃに沿って変位可能である。具体的に、保持部４４の外径は、被接続部３２の内径よりも小さい。保持部４４は、付勢部４６の付勢力の作用方向（図１では上向き）と平行な中心軸Ｃ回りに供給体５０が回転するのを規制するように当該供給体５０を保持する。本実施形態では、図２に示されるように、保持部４４には、十字状の溝４５が形成されている。この溝４５内に、後述の供給体５０の軸部６２が挿入されることによって供給体５０の基体３０に対する相対回転が規制される。 The holding portion 44 can be displaced along the central axis C inside the connected portion 32 while holding the supply body 50. Specifically, the outer diameter of the holding portion 44 is smaller than the inner diameter of the connected portion 32. The holding portion 44 holds the feeder 50 so as to restrict the rotation of the feeder 50 around the central axis C parallel to the direction of action of the urging force of the urging portion 46 (upward in FIG. 1). In the present embodiment, as shown in FIG. 2, the holding portion 44 is formed with a cross-shaped groove 45. By inserting the shaft portion 62 of the supply body 50, which will be described later, into the groove 45, the relative rotation of the supply body 50 with respect to the base 30 is restricted.

付勢部４６は、被接続部３２の内周面のうちの収容部１２に近い側（図１では下側）の端部と保持部４４とを接続する螺旋状のばね部材である。この付勢部４６の伸縮により、保持部４４、すなわち、供給体５０が付勢部４６の付勢力の作用方向と平行な方向に変位する。図３に示されるように、付勢部４６は、自然長において保持部４４の上端面が抜止部４０よりも上方に位置するように被接続部３２と保持部４４とを接続している。そして、図１に示されるように、供給体５０が抜止部４０に当接する状態では、付勢部４６は自然長よりも圧縮されている。つまり、付勢部４６は、供給体５０を常時抜止部４０に押し付けており、図１は、供給体５０が抜止部４０に押し付けられることにより、容器１０内が密閉された状態を示している。 The urging portion 46 is a spiral spring member that connects the end portion of the inner peripheral surface of the connected portion 32 that is closer to the accommodating portion 12 (lower side in FIG. 1) and the holding portion 44. Due to the expansion and contraction of the urging portion 46, the holding portion 44, that is, the feeder 50 is displaced in a direction parallel to the acting direction of the urging force of the urging portion 46. As shown in FIG. 3, the urging portion 46 connects the connected portion 32 and the holding portion 44 so that the upper end surface of the holding portion 44 is located above the retaining portion 40 in its natural length. Then, as shown in FIG. 1, in the state where the feeder 50 is in contact with the retaining portion 40, the urging portion 46 is compressed more than the natural length. That is, the urging unit 46 constantly presses the feeder 50 against the retaining portion 40, and FIG. 1 shows a state in which the inside of the container 10 is sealed by pressing the feeder 50 against the retaining portion 40. ..

規制部３４は、被接続部３２と抜止部４０との間に形成されている。規制部３４は、押付部４２の押付力に抗するように供給体５０が押圧されたときに当該供給体５０と当接することにより供給体５０の変位を規制する。規制部３４は、被接続部３２の中心軸Ｃと直交する円環状の規制面３６と、規制面３６から外向きに突出するとともに、環状でかつ供給体５０に線接触する形状を有する環状突起３８と、を有している。なお、環状突起３８は、省略されてもよい。 The regulating portion 34 is formed between the connected portion 32 and the retaining portion 40. When the feeder 50 is pressed against the pressing force of the pressing portion 42, the regulating unit 34 regulates the displacement of the feeder 50 by coming into contact with the feeder 50. The regulating portion 34 has an annular regulating surface 36 orthogonal to the central axis C of the connected portion 32, and an annular protrusion having a shape that protrudes outward from the regulating surface 36 and is annular and has a shape that makes line contact with the feeder 50. 38 and. The annular protrusion 38 may be omitted.

供給体５０は、基体３０に保持されており、かつ、容器１０内の閉塞及び被供給部（皮膚等）への薬液の供給が可能である。具体的に、供給体５０は、供給体本体５２と、軸部６２と、を有している。供給体本体５２と軸部６２とは、一体成形されている。 The feeder 50 is held by the substrate 30 and can block the container 10 and supply the chemical solution to the supplied portion (skin or the like). Specifically, the feeder 50 has a feeder main body 52 and a shaft portion 62. The feeder main body 52 and the shaft portion 62 are integrally molded.

供給体本体５２は、被供給部に薬液を供給する供給面５４と、複数の（本実施形態では３つの）膨出部５６と、抜止部４０に当接する当接部５８と、規制部３４と対向する対向部６０と、を有している。 The feeder main body 52 includes a supply surface 54 that supplies the chemical solution to the supplied portion, a plurality of bulging portions 56 (three in this embodiment), a contact portion 58 that abuts on the retaining portion 40, and a regulating portion 34. It has an opposing portion 60 that faces the surface.

供給面５４は、容器１０の外側に向かって凸となるように湾曲する形状を有している。 The supply surface 54 has a shape curved so as to be convex toward the outside of the container 10.

各膨出部５６は、供給面５４から外向きに膨出する形状を有している。つまり、各膨出部５６の曲率半径は、供給面５４の曲率半径よりも小さく設定されている。図４及び図５に示されるように、各膨出部５６は、供給面５４のうちの当該供給面５４の中心から離間した部位に形成されている。本実施形態では、各膨出部５６は、前記中心の周りに等間隔に並ぶように配置されている。 Each bulging portion 56 has a shape that bulges outward from the supply surface 54. That is, the radius of curvature of each bulging portion 56 is set smaller than the radius of curvature of the supply surface 54. As shown in FIGS. 4 and 5, each bulging portion 56 is formed at a portion of the supply surface 54 that is separated from the center of the supply surface 54. In the present embodiment, the bulging portions 56 are arranged so as to be arranged at equal intervals around the center.

当接部５８は、抜止部４０に対して前記付勢力（押付力）の作用方向に当接する。当接部５８は、供給面５４の外縁に接続されている。当接部５８は、供給面５４から離間するにしたがって次第に当該当接部５８の外径が大きくなる形状（円錐台状）に形成されている。この当接部５８は、図７に示されるように、抜止部４０から離間することにより供給体５０と抜止部４０との間に薬液の容器１０外への供給流路Ｓを形成する。この状態では、被供給部への薬液の供給が可能となる。そして、当接部５８は、図１に示されるように、抜止部４０と接触（密着）することにより供給流路Ｓを遮断する。この状態では、容器１０内が密閉される。 The contact portion 58 contacts the retaining portion 40 in the direction of action of the urging force (pressing force). The contact portion 58 is connected to the outer edge of the supply surface 54. The contact portion 58 is formed in a shape (conical cone shape) in which the outer diameter of the contact portion 58 gradually increases as the distance from the supply surface 54 increases. As shown in FIG. 7, the contact portion 58 forms a supply flow path S for the chemical solution to the outside of the container 10 between the supply body 50 and the retaining portion 40 by being separated from the retaining portion 40. In this state, the chemical solution can be supplied to the supplied portion. Then, as shown in FIG. 1, the contact portion 58 shuts off the supply flow path S by contacting (adhering) with the retaining portion 40. In this state, the inside of the container 10 is sealed.

軸部６２は、供給体本体５２のうちの供給面５４とは反対側の面から当該面と垂直に延びる形状を有している。図４及び図６に示されるように、軸部６２は、中央軸６４と、複数の（本実施形態では４つの）側板６６と、を有している。 The shaft portion 62 has a shape extending perpendicularly to the surface of the main body 52 of the feeder body 52 on the side opposite to the supply surface 54. As shown in FIGS. 4 and 6, the shaft portion 62 has a central shaft 64 and a plurality of (four in this embodiment) side plates 66.

中央軸６４は、円柱状である。この中央軸６４は、保持部４４の溝４５内に挿通可能な外径に設定される。 The central axis 64 is columnar. The central shaft 64 is set to an outer diameter that can be inserted into the groove 45 of the holding portion 44.

各側板６６は、中央軸６４から当該中央軸６４の径方向の外向きに突出する形状を有している。各側板６６は、中央軸６４の周方向に沿って９０度間隔で配置されている。各側板６６は、溝４５内に挿通可能な厚さに設定される。これらの側板６６が溝４５内に挿通されることにより、供給体５０の基体３０に対する前記中心軸Ｃ回りの相対回転が規制される。なお、ここでいう「規制」とは、供給体５０の基体３０に対する相対回転を一切許容しないことを意味するのではなく、供給体５０の周方向への変位量が予め設定された許容範囲内に収まるように前記相対回転を規制することを意味する。 Each side plate 66 has a shape that projects outward from the central shaft 64 in the radial direction of the central shaft 64. The side plates 66 are arranged at intervals of 90 degrees along the circumferential direction of the central axis 64. Each side plate 66 is set to a thickness that allows it to be inserted into the groove 45. By inserting these side plates 66 into the groove 45, the relative rotation of the feeder 50 with respect to the substrate 30 around the central axis C is restricted. The term "regulation" here does not mean that the relative rotation of the feeder 50 with respect to the substrate 30 is not allowed at all, but the amount of displacement of the feeder 50 in the circumferential direction is within a preset allowable range. It means that the relative rotation is regulated so as to fit in.

対向部６０は、軸部６２が溝４５内に挿入された状態において規制部３４と対向する部位である。対向部６０は、平坦に形成されている。図７に示されるように、対向部６０は、供給面５４ないし膨出部５６が付勢部４６の付勢力に抗して押圧されたときに規制部３４の環状突起３８と当接（線接触）する。この状態では、薬液の容器１０外への流出が規制される。 The facing portion 60 is a portion facing the regulating portion 34 when the shaft portion 62 is inserted into the groove 45. The facing portion 60 is formed flat. As shown in FIG. 7, the facing portion 60 comes into contact with the annular projection 38 of the regulating portion 34 when the supply surface 54 to the bulging portion 56 is pressed against the urging force of the urging portion 46 (line). Contact. In this state, the outflow of the chemical solution to the outside of the container 10 is restricted.

また、図８に示されるように、抜止部４０は、前記中心軸Ｃに対して軸部６２の中心軸Ａが傾斜するように供給体５０が傾斜するのを許容する形状を有する。具体的に、抜止部４０は、供給体５０のうちの前記中心軸Ａから当該中心軸Ａと直交する方向に離間した偏倚部（例えば膨出部５６）が押圧されたときに、前記中心軸Ａを基準として供給体５０のうちの偏倚部と反対側に位置する部位と当該抜止部４０との接触箇所Ｐを支点として対向部６０が環状突起３８に当接するまで供給体５０が基体３０に対して傾動するのを許容する形状を有する。 Further, as shown in FIG. 8, the retaining portion 40 has a shape that allows the feeder 50 to be tilted so that the central axis A of the shaft portion 62 is tilted with respect to the central shaft C. Specifically, the retaining portion 40 is the central axis of the feeder 50 when a biased portion (for example, a bulging portion 56) separated from the central axis A in a direction orthogonal to the central axis A is pressed. The feeder 50 is attached to the base 30 until the facing portion 60 abuts on the annular protrusion 38 with the contact portion P between the portion of the feeder 50 located on the opposite side of the deviation portion and the retaining portion 40 as a fulcrum with reference to A. It has a shape that allows it to tilt.

キャップ７０は、口部１４に螺合される。具体的に、キャップ７０の内周面には、口部１４に形成された雄ねじ部１５に螺合する雌ねじ部７２が形成されている。また、キャップ７０は、抜止部４０に当接することによって容器１０内を密閉する環状の突出部７４を有している。 The cap 70 is screwed into the mouth portion 14. Specifically, on the inner peripheral surface of the cap 70, a female screw portion 72 that is screwed into the male screw portion 15 formed in the mouth portion 14 is formed. Further, the cap 70 has an annular protruding portion 74 that seals the inside of the container 10 by abutting on the retaining portion 40.

次に、薬液供給器具１の使用方法について説明する。以下では、被供給部が皮膚の場合、つまり、本薬液供給器具１を用いて皮膚に薬液を塗布する場合について説明する。 Next, a method of using the chemical solution supply device 1 will be described. Hereinafter, the case where the supplied portion is the skin, that is, the case where the drug solution is applied to the skin by using the drug solution supply device 1 will be described.

まず、供給面５４が下を向く姿勢で当該供給面５４を皮膚に押し付ける。このとき、対向部６０が環状突起３８に接触するまで供給体５０が付勢部４６の付勢力に抗して押圧される。これにより、図７に示されるように、当接部５８と抜止部４０との間に供給流路Ｓが形成されるので、当該供給流路Ｓを通じて容器１０内の薬液が容器１０外に供給される。一方、環状突起３８と対向部６０との接触により容器１０内が密閉されるので、それ以上の薬液の供給は停止される。 First, the supply surface 54 is pressed against the skin in a posture in which the supply surface 54 faces downward. At this time, the feeder 50 is pressed against the urging force of the urging portion 46 until the opposing portion 60 comes into contact with the annular projection 38. As a result, as shown in FIG. 7, a supply flow path S is formed between the contact portion 58 and the retaining portion 40, so that the chemical solution in the container 10 is supplied to the outside of the container 10 through the supply flow path S. Will be done. On the other hand, since the inside of the container 10 is sealed by the contact between the annular protrusion 38 and the facing portion 60, the supply of the chemical solution beyond that is stopped.

そして、そのまま薬液供給器具１を皮膚に沿って移動させることにより、薬液が皮膚の所望する領域に塗布される。 Then, by moving the drug solution supply device 1 as it is along the skin, the drug solution is applied to a desired region of the skin.

以上に説明したように、本薬液供給器具１では、付勢部４６の付勢力に抗して供給体５０が押圧されたときに供給流路Ｓを通じて薬液が供給されるので、薬液の供給不足が回避され、さらに、供給体５０が規制部３４に当接することによって供給体５０の変位（押圧ストローク）が規制されるので、供給流路Ｓを通じた薬液の過剰供給が抑制される。よって、薬液の供給量を一定の範囲内に収めることが可能となる。 As described above, in the chemical solution supply device 1, when the feeder 50 is pressed against the urging force of the urging portion 46, the chemical solution is supplied through the supply flow path S, so that the chemical solution supply is insufficient. Further, the displacement (pressing stroke) of the supply body 50 is regulated by the supply body 50 coming into contact with the regulation portion 34, so that the excessive supply of the chemical solution through the supply flow path S is suppressed. Therefore, it is possible to keep the supply amount of the chemical solution within a certain range.

また、本実施形態では、規制部３４は、対向部６０に線接触する環状突起３８を有しているので、対向部６０が環状突起３８に接触することによって薬液の流出が有効に規制される。よって、薬液の過剰供給がより確実に抑制される。 Further, in the present embodiment, since the regulating portion 34 has an annular protrusion 38 that makes line contact with the facing portion 60, the outflow of the chemical solution is effectively regulated by the contacting the facing portion 60 with the annular protrusion 38. .. Therefore, the excessive supply of the chemical solution is more reliably suppressed.

また、保持部４４は、前記付勢力の作用方向と平行な中心軸Ｃ回りに供給体５０が回転するのを規制するように当該供給体５０を保持するので、環状突起３８の摩耗が低減される。例えば、供給体５０が保持部４４に対して相対回転可能であれば、供給体５０が環状突起３８に接触した状態で当該供給体５０が保持部４４に対して相対回転した場合に環状突起３８の摩耗が生じるが、本薬液供給器具１では、供給体５０の保持部４４に対する相対回転が規制されるので、環状突起３８の摩耗が低減される。 Further, since the holding portion 44 holds the feeder 50 so as to restrict the rotation of the feeder 50 around the central axis C parallel to the acting direction of the urging force, the wear of the annular projection 38 is reduced. NS. For example, if the feeder 50 can rotate relative to the holding portion 44, the annular projection 38 when the feeder 50 rotates relative to the holding portion 44 while the feeder 50 is in contact with the annular projection 38. However, in the chemical solution supply device 1, the relative rotation of the feeder 50 with respect to the holding portion 44 is restricted, so that the wear of the annular protrusion 38 is reduced.

また、抜止部４０は、前記中心軸Ｃに対して軸部６２の中心軸Ａが傾斜するように供給体５０が傾斜するのを許容する形状を有するので、供給体５０のうちの前記偏倚部が押圧された場合であっても、供給流路Ｓが確保され、これにより薬液がスムーズに供給される。 Further, since the retaining portion 40 has a shape that allows the supply body 50 to be tilted so that the central axis A of the shaft portion 62 is tilted with respect to the central shaft C, the deviation portion of the supply body 50 is said to be tilted. Is pressed, the supply flow path S is secured, whereby the chemical solution is smoothly supplied.

さらに、供給体５０の保持部４４に対する相対回転が規制されているので、供給体５０のうちの前記偏倚部に作用した外力は、供給体５０を傾ける方向の押圧力として作用しやすくなる。よって、供給体５０が傾斜しやすくなるので、薬液の供給量が有効に確保される。 Further, since the relative rotation of the supply body 50 with respect to the holding portion 44 is regulated, the external force acting on the biased portion of the supply body 50 tends to act as a pressing force in the direction of tilting the supply body 50. Therefore, the feeder 50 is likely to be tilted, so that the supply amount of the chemical solution is effectively secured.

また、各膨出部５６は、供給面５４のうちの当該供給面５４の中心から離間した部位に形成されているので、当該膨出部５６が押圧された場合に供給体５０の傾斜が促進され、これにより供給流路Ｓが有効に形成される。 Further, since each bulging portion 56 is formed at a portion of the supply surface 54 that is separated from the center of the supply surface 54, the inclination of the supply body 50 is promoted when the bulging portion 56 is pressed. As a result, the supply flow path S is effectively formed.

（第２実施形態）
次に、本発明の第２実施形態の薬液供給器具１について、図１１〜図１４を参照しながら説明する。なお、本実施形態では、第１実施形態と異なる部分についてのみ説明が行われ、第１実施形態と同じ構造、作用、効果等の説明は省略される。(Second Embodiment)
Next, the chemical solution supply device 1 of the second embodiment of the present invention will be described with reference to FIGS. 11 to 14. In this embodiment, only the parts different from those in the first embodiment will be described, and the description of the same structure, action, effect, etc. as in the first embodiment will be omitted.

本実施形態では、膨出部５６の供給面５４からの膨出量は、第１実施形態のそれよりも大きく設定されている。そして、各膨出部５６の背面側（図１１の下側）、より詳細には、前記押付力の作用方向と平行な方向について各膨出部５６と重なる位置には、３本の補強リブ６１が形成されている。各膨出部５６は、環状突起３８の径方向について当該環状突起３８よりも内側に形成されている。この点は、第１実施形態においても同様である。 In the present embodiment, the amount of swelling from the supply surface 54 of the bulging portion 56 is set to be larger than that of the first embodiment. Then, three reinforcing ribs are located on the back surface side (lower side of FIG. 11) of each bulging portion 56, more specifically, at a position overlapping each bulging portion 56 in a direction parallel to the acting direction of the pressing force. 61 is formed. Each bulging portion 56 is formed inside the annular projection 38 in the radial direction of the annular projection 38. This point is the same in the first embodiment.

また、軸部６２の長さは、第１実施形態のそれよりも短く設定されている。 Further, the length of the shaft portion 62 is set shorter than that of the first embodiment.

図１１〜図１３に示されるように、抜止部４０の外周面には、薬液を保持する薬液保持部４８が形成されている。この薬液保持部４８は、抜止部４０の外周面の他の部位から当該抜止部４０の径方向（図１１の左右方向）の内向きに窪むとともに当該抜止部４０の周方向に連続的につながる形状を有する。つまり、薬液保持部４８は、毛細管現象を利用して薬液を保持する。 As shown in FIGS. 11 to 13, a chemical solution holding portion 48 for holding the chemical solution is formed on the outer peripheral surface of the retaining portion 40. The chemical holding portion 48 is recessed inward in the radial direction (horizontal direction in FIG. 11) of the retaining portion 40 from another portion on the outer peripheral surface of the retaining portion 40, and is continuously connected in the circumferential direction of the retaining portion 40. Has a shape. That is, the chemical solution holding unit 48 holds the chemical solution by utilizing the capillary phenomenon.

また、本実施形態では、キャップ７０は、当該キャップ７０が口部１４に接続（螺合）された状態において供給体５０の対向部６０が規制部３４の環状突起３８に接触するように当該供給体５０を押圧する押圧面７１を有している。換言すれば、キャップ７０が口部１４に接続されたときに対向部６０が環状突起３８に押し付けられるように各膨出部５６の膨出量が設定されている。 Further, in the present embodiment, the cap 70 is supplied so that the facing portion 60 of the feeder 50 comes into contact with the annular projection 38 of the regulating portion 34 in a state where the cap 70 is connected (screwed) to the mouth portion 14. It has a pressing surface 71 that presses the body 50. In other words, the bulging amount of each bulging portion 56 is set so that the facing portion 60 is pressed against the annular protrusion 38 when the cap 70 is connected to the mouth portion 14.

本実施形態では、突出部７４は、キャップ７０が口部１４に接続された状態における押圧面７１の供給体５０の押圧量を規制する機能を有している。つまり、本実施形態では、突出部７４は、「ストッパ」として機能する。そして、抜止部４０の上面がストッパを受ける受け部４１に相当する。 In the present embodiment, the protruding portion 74 has a function of regulating the pressing amount of the feeder 50 of the pressing surface 71 in a state where the cap 70 is connected to the mouth portion 14. That is, in the present embodiment, the protruding portion 74 functions as a "stopper". The upper surface of the retaining portion 40 corresponds to the receiving portion 41 that receives the stopper.

図１２は、キャップ７０が口部１４に接続（螺合）される過程において押圧面７１と供給体５０の各膨出部５６とが接触した瞬間を示している。この図１２に示されるように、押圧面７１と各膨出部５６とが接触したときにおける前記ストッパ（突出部７４）と受け部４１との距離Ｄ１は、押圧面７１と各膨出部５６とが接触したときにおける対向部６０と環状突起３８との距離Ｄ２よりも大きい。また、各膨出部５６のうち環状突起３８の中心軸に最も近い位置に形成された膨出部５６と押圧面７１との接触部（点接触及び面接触を含む）から環状突起３８までの環状突起３８の径方向についての距離Ｄ３は、膨出部５６と押圧面７１とが接触したときにおける前記ストッパと受け部４１との距離Ｄ１と対向部６０と環状突起３８との距離Ｄ２との差の０．１倍以上１８０倍以下であることが好ましく、０．１倍以上９０倍以下であることがより好ましい。 FIG. 12 shows the moment when the pressing surface 71 and each of the bulging portions 56 of the feeder 50 come into contact with each other in the process of connecting (screwing) the cap 70 to the mouth portion 14. As shown in FIG. 12, the distance D1 between the stopper (protruding portion 74) and the receiving portion 41 when the pressing surface 71 and each bulging portion 56 come into contact is determined by the pressing surface 71 and each bulging portion 56. It is larger than the distance D2 between the facing portion 60 and the annular protrusion 38 when they come into contact with each other. Further, from the contact portion (including point contact and surface contact) between the bulging portion 56 formed at the position closest to the central axis of the annular protrusion 38 and the pressing surface 71 among the bulging portions 56 to the annular protrusion 38. The distance D3 in the radial direction of the annular protrusion 38 is the distance D1 between the stopper and the receiving portion 41 when the bulging portion 56 and the pressing surface 71 come into contact with each other, and the distance D2 between the facing portion 60 and the annular protrusion 38. The difference is preferably 0.1 times or more and 180 times or less, and more preferably 0.1 times or more and 90 times or less.

本実施形態では、基体３０は、ポリアセタール樹脂（ＰＯＭ）で形成されている。これにより、付勢部４６の塑性変形（付勢力の低下）が抑制される。供給体５０も、ポリアセタール樹脂で形成されてもよい。ただし、供給体５０は、基体３０を構成するポリアセタール樹脂よりも低い硬度を有する樹脂材料で形成されることが好ましい。本実施形態では、各膨出部５６の背面側にリブ６１が設けられているため、前記樹脂によって供給体５０を成形した際における各膨出部５６へのヒケの発生が抑制される。さらに、各膨出部５６の背面側に各リブ６１が設けられることによって、各膨出部５６と位置ずれして各リブ６１が設けられる場合に比べ、膨出部５６と押圧面７１との接触による押圧力が膨出部５６に作用する際の供給面５４の変形が効果的に抑制されるので、供給面５４の破損（割れ等）が抑制される。 In this embodiment, the substrate 30 is made of polyacetal resin (POM). As a result, plastic deformation (decrease in urging force) of the urging portion 46 is suppressed. The feeder 50 may also be made of a polyacetal resin. However, the feeder 50 is preferably formed of a resin material having a hardness lower than that of the polyacetal resin constituting the substrate 30. In the present embodiment, since the rib 61 is provided on the back surface side of each bulging portion 56, the occurrence of sink marks on each bulging portion 56 when the feeder 50 is molded by the resin is suppressed. Further, since each rib 61 is provided on the back surface side of each bulging portion 56, the bulging portion 56 and the pressing surface 71 are provided as compared with the case where each rib 61 is provided so as to be displaced from each bulging portion 56. Since the deformation of the supply surface 54 when the pressing force due to the contact acts on the bulging portion 56 is effectively suppressed, the supply surface 54 is suppressed from being damaged (cracked or the like).

以上に説明したように、本実施形態の薬液供給器具１では、抜止部４０の外周面に薬液保持部４８が形成されているので、供給体５０外に薬液が漏れたとしても、その薬液が薬液保持部４８に保持される。よって、供給体５０外に漏れた薬液が収容部１０の外周面に至ることが抑制される。 As described above, in the chemical solution supply device 1 of the present embodiment, since the chemical solution holding portion 48 is formed on the outer peripheral surface of the retaining portion 40, even if the chemical solution leaks out of the feeder 50, the chemical solution is released. It is held by the chemical holding portion 48. Therefore, it is suppressed that the chemical solution leaked to the outside of the feeder 50 reaches the outer peripheral surface of the accommodating portion 10.

また、薬液保持部４８は、抜止部４０の外周面の他の部位から当該抜止部４０の径方向の内向きに窪むとともに当該抜止部４０の周方向に連続的につながる形状を有するので、供給体５０外に漏れた薬液は、毛細管現象によって有効に薬液保持部４８に保持される。 Further, since the chemical liquid holding portion 48 has a shape of being recessed inward in the radial direction of the retaining portion 40 from another portion of the outer peripheral surface of the retaining portion 40 and continuously connected in the circumferential direction of the retaining portion 40, it is supplied. The chemical solution leaked to the outside of the body 50 is effectively held in the chemical solution holding portion 48 by the capillary phenomenon.

なお、今回開示された上記実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 It should be noted that the above-described embodiment disclosed this time is merely an example in all respects and is not restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the above-described embodiment, and further includes all modifications within the meaning and scope equivalent to the scope of claims.

例えば、供給体５０の基体３０に対する前記中心軸回りの相対回転が規制されるのであれば、保持部４４の溝４５の形状及び軸部６２の形状は、上記の例に限られない。 For example, if the relative rotation of the feeder 50 with respect to the base 30 around the central axis is restricted, the shape of the groove 45 of the holding portion 44 and the shape of the shaft portion 62 are not limited to the above examples.

また、図９は、上記実施形態の薬液供給具２０の第１変形例を示している。この薬液供給具２１では、供給面５４に抵抗発生部５７Ａが形成されている。抵抗発生部５７Ａは、供給面５４と被供給部との摩擦抵抗よりも当該抵抗発生部５７Ａと被供給部との摩擦抵抗を大きくする。この例では、抵抗発生部５７Ａは、前記中心軸Ａを中心とする同心円状に配置された複数の円筒により構成されている。この態様では、供給体５０を被供給部（皮膚）に対して押し付けた状態から当該薬液供給器具を被供給部に沿って移動させたときにおける抵抗発生部５７Ａと被供給部との摩擦抵抗が、供給面５４と被供給部との摩擦抵抗よりも大きくなるため、供給体５０が基体３０に対して傾斜しやすくなる。よって、有効に供給流路Ｓが形成される。さらに、抵抗発生部５７Ａは、各円筒間に薬液を保持する機能及び皮膚を刺激することによって皮膚の痒みを緩和させる機能をも有している。 Further, FIG. 9 shows a first modification of the chemical solution feeder 20 of the above embodiment. In the chemical solution supply tool 21, a resistance generating portion 57A is formed on the supply surface 54. The resistance generating portion 57A makes the frictional resistance between the resistance generating portion 57A and the supplied portion larger than the frictional resistance between the supply surface 54 and the supplied portion. In this example, the resistance generating portion 57A is composed of a plurality of cylinders arranged concentrically around the central axis A. In this aspect, the frictional resistance between the resistance generating portion 57A and the supplied portion when the chemical solution supplying device is moved along the supplied portion from the state where the feeder 50 is pressed against the supplied portion (skin) is generated. Since it is larger than the frictional resistance between the supply surface 54 and the supplied portion, the supply body 50 is likely to be inclined with respect to the substrate 30. Therefore, the supply flow path S is effectively formed. Further, the resistance generating portion 57A also has a function of holding a chemical solution between the cylinders and a function of relieving itching of the skin by stimulating the skin.

また、図１０は、上記実施形態の薬液供給具２０の第２変形例を示している。この薬液供給具２２においても、供給面５４に抵抗発生部５７Ｂが設けられている。この例では、抵抗発生部５７Ｂは、それぞれが供給面５４から突出する複数の小突起により構成されている。この態様においても、図９に示される薬液供給具２１と同じ効果が得られる。 Further, FIG. 10 shows a second modification of the chemical solution feeder 20 of the above embodiment. Also in this chemical solution supply tool 22, a resistance generating portion 57B is provided on the supply surface 54. In this example, the resistance generating portion 57B is composed of a plurality of small protrusions, each of which protrudes from the supply surface 54. Also in this aspect, the same effect as that of the chemical solution supply tool 21 shown in FIG. 9 can be obtained.

以上に説明した実施形態には、以下の構成を有する発明が含まれている。 The embodiments described above include inventions having the following configurations.

上記実施形態の薬液供給器具は、薬液を収容可能な収容部及び前記収容部に接続されており特定方向に開口する口部を有する容器と、前記口部に接続可能で、かつ、当該口部に接続された状態において前記容器内が密閉された状態と前記収容部内の前記薬液を前記容器外に供給可能な状態とを切り替え可能な薬液供給具と、を備え、前記薬液供給具は、前記口部に接続可能で、かつ、前記容器内と前記容器外とを連通させる形状を有する基体と、前記基体に保持されており、かつ、前記容器内の閉塞及び被供給部への前記薬液の供給が可能な供給体と、を有し、前記基体は、当該基体からの前記供給体の離脱を阻止するように前記口部を基準として前記収容部と反対側から前記供給体に接触する抜止部と、前記容器内が閉塞されるように前記供給体を前記抜止部に向けて押し付ける押付部と、前記押付部の押付力に抗するように前記供給体が押圧されたときに当該供給体と当接することにより前記供給体の変位を規制する規制部と、を有し、前記供給体は、前記抜止部から離間することにより当該供給体と前記抜止部との間に前記薬液の前記容器外への供給流路を形成するとともに、前記抜止部と接触することにより前記供給流路を遮断する。 The chemical solution supply device of the above embodiment includes a container capable of accommodating a chemical solution, a container connected to the accommodating portion and having a mouth portion that opens in a specific direction, and a mouth portion that is connectable to the mouth portion and has the mouth portion. The chemical solution supply tool includes a chemical solution supply tool that can switch between a state in which the inside of the container is sealed and a state in which the chemical solution in the storage portion can be supplied to the outside of the container in a state of being connected to the container. A substrate that can be connected to the mouth and has a shape that allows the inside of the container and the outside of the container to communicate with each other, and the chemical solution that is held by the substrate and that closes the inside of the container and to the supplied portion. The substrate has a feeder capable of supplying the substrate, and the substrate comes into contact with the feeder from the side opposite to the housing portion with reference to the mouth portion so as to prevent the feeder from detaching from the substrate. A portion, a pressing portion that pushes the feeder toward the retaining portion so that the inside of the container is closed, and a feeder that is pressed against the pressing force of the pressing portion. The container has a regulating portion that regulates the displacement of the feeder by abutting with the container, and the feeder is separated from the retaining portion so that the container of the chemical solution is placed between the feeder and the retaining portion. The supply flow path to the outside is formed, and the supply flow path is shut off by contacting with the retaining portion.

本薬液供給器具では、押付部の押付力に抗して供給体が押圧されたときに供給流路を通じて薬液が供給されるので、薬液の供給不足が回避され、さらに、供給体が規制部に当接することによって供給体の変位（押圧ストローク）が規制されるので、供給流路を通じた薬液の過剰供給が抑制される。よって、薬液の供給量を一定の範囲内に収めることが可能となる。 In this drug solution supply device, when the feeder is pressed against the pressing force of the pressing part, the drug solution is supplied through the supply flow path, so that the supply shortage of the drug solution is avoided, and the feeder is placed in the regulation section. Since the displacement (pressing stroke) of the feeder is regulated by the contact, the excessive supply of the chemical solution through the supply flow path is suppressed. Therefore, it is possible to keep the supply amount of the chemical solution within a certain range.

また、前記薬液供給器具において、前記規制部は、前記押付力の作用方向と直交する環状の規制面と、前記規制面から外向きに突出するとともに、環状でかつ前記供給体に線接触する形状を有する環状突起と、を有することが好ましい。 Further, in the chemical solution supply device, the restricting portion has an annular regulation surface orthogonal to the direction of action of the pressing force, and a shape that protrudes outward from the regulation surface and is annular and in line contact with the feeder. It is preferable to have an annular protrusion having.

このようにすれば、供給体が環状突起に接触することによって薬液の流出が有効に規制されるので、薬液の過剰供給がより確実に抑制される。 In this way, the outflow of the chemical solution is effectively regulated by the contact of the feeder with the annular projection, so that the excessive supply of the chemical solution is more reliably suppressed.

この場合において、前記押付部は、前記押付力の作用方向と平行な中心軸回りに前記供給体が回転するのを規制するように当該供給体を保持する保持部を有することが好ましい。 In this case, it is preferable that the pressing portion has a holding portion that holds the feeder so as to restrict the rotation of the feeder around a central axis parallel to the direction of action of the pressing force.

このようにすれば、環状突起の摩耗が低減される。例えば、供給体が保持部に対して相対回転可能であれば、供給体が環状突起に接触した状態で当該供給体が保持部に対して相対回転した場合に環状突起の摩耗が生じるが、本薬液供給器具では、供給体の保持部に対する相対回転が規制されるので、環状突起の摩耗が低減される。なお、ここでいう「規制」とは、供給体の保持部に対する相対回転を一切許容しないことを意味するのではなく、供給体の周方向への変位量が予め設定された許容範囲内に収まるように前記相対回転を規制することを意味する。 In this way, the wear of the annular protrusion is reduced. For example, if the feeder can rotate relative to the holding portion, the annular projection wears when the feeder rotates relative to the holding portion while the feeder is in contact with the annular projection. In the chemical supply device, the relative rotation of the feeder with respect to the holding portion is restricted, so that the wear of the annular protrusion is reduced. The term "regulation" here does not mean that the relative rotation of the feeder with respect to the holding portion is not allowed at all, but the amount of displacement of the feeder in the circumferential direction falls within a preset allowable range. It means that the relative rotation is regulated as described above.

また、前記薬液供給器具において、前記抜止部は、前記供給体のうちの前記押付力の作用方向と平行な中心軸から当該中心軸と直交する方向に離間した偏倚部が押圧されたときに、前記中心軸を基準として前記供給体のうちの前記偏倚部と反対側に位置する部位と当該抜止部との接触箇所を支点として前記供給体が前記規制部に当接するまで前記供給体が前記基体に対して傾動するのを許容する形状を有することが好ましい。 Further, in the chemical solution supply device, when the detent portion of the feeder is pressed from the central axis parallel to the action direction of the pressing force in the direction orthogonal to the central axis, the retaining portion is pressed. With the central axis as a reference, the supply body stays on the substrate until the supply body comes into contact with the regulation portion with the contact point between the portion of the supply body located on the opposite side of the deviation portion and the retaining portion as a fulcrum. It is preferable to have a shape that allows it to tilt with respect to.

このようにすれば、供給体のうちの偏倚部が押圧された場合であっても、薬液がスムーズに供給される。具体的に、抜止部は、偏倚部が押圧されたときに、供給体と抜止部との接触箇所を支点として供給体が規制部に当接するまで供給体が基体に対して傾動するのを許容する形状を有するので、供給流路が確保される。 In this way, the chemical solution is smoothly supplied even when the eccentric portion of the feeder is pressed. Specifically, the retaining portion allows the feeder to tilt with respect to the substrate when the deviation portion is pressed, with the contact point between the feeder and the retaining portion as a fulcrum until the feeder abuts on the regulating portion. Since it has a shape that allows it to be supplied, a supply flow path is secured.

また、前記薬液供給器具において、前記供給体は、前記被供給部に接触可能な供給面と、前記供給面のうちの前記押付力の作用方向と平行な中心軸の周りの部位に形成されており、かつ、前記供給面から外向きに膨出する形状を有する少なくとも一つの膨出部と、を有することが好ましい。 Further, in the chemical solution supply device, the feeder is formed on a supply surface that can come into contact with the supplied portion and a portion of the supply surface around a central axis that is parallel to the direction of action of the pressing force. It is preferable to have at least one bulging portion having a shape that bulges outward from the supply surface.

このようにすれば、膨出部が押圧された場合に供給体の傾斜が促進されるので、有効に供給流路が形成される。 By doing so, the inclination of the feeder is promoted when the bulging portion is pressed, so that the supply flow path is effectively formed.

また、前記薬液供給器具において、前記抜止部の外周面及び前記口部の外周面の少なくとも一方には、前記薬液を保持する薬液保持部が形成されていることが好ましい。 Further, in the chemical solution supply device, it is preferable that a chemical solution holding portion for holding the chemical solution is formed on at least one of the outer peripheral surface of the retaining portion and the outer peripheral surface of the mouth portion.

このようにすれば、供給体外に薬液が漏れたとしても、その薬液が薬液保持部に保持される。よって、供給体外に漏れた薬液が収容部の外周面に至ることが抑制される。 In this way, even if the chemical solution leaks out of the supply body, the chemical solution is held in the chemical solution holding portion. Therefore, it is possible to prevent the chemical solution leaking from the supply body from reaching the outer peripheral surface of the accommodating portion.

具体的に、前記薬液保持部は、前記抜止部の外周面に形成されており、前記薬液保持部は、前記抜止部の外周面の他の部位から当該抜止部の径方向の内向きに窪むとともに当該抜止部の周方向に連続的につながる形状を有することが好ましい。 Specifically, the chemical liquid holding portion is formed on the outer peripheral surface of the retaining portion, and the chemical liquid holding portion is recessed inward in the radial direction of the retaining portion from another portion of the outer peripheral surface of the retaining portion. In addition, it is preferable to have a shape that is continuously connected in the circumferential direction of the retaining portion.

このようにすれば、供給体外に漏れた薬液がより確実に薬液保持部に保持されるので、当該薬液が収容部の外周面に至ることがより確実に抑制される。 By doing so, the chemical solution leaked to the outside of the supply body is more reliably held in the chemical solution holding portion, so that the chemical solution is more reliably suppressed from reaching the outer peripheral surface of the accommodating portion.

また、上記実施形態の薬液供給具は、薬液を収容可能な収容部及び前記収容部に接続されており特定方向に開口する口部を有する容器の前記口部に接続可能で、かつ、当該口部に接続された状態において前記容器内が密閉された状態と前記収容部内の前記薬液を前記容器外に供給可能な状態とを切り替え可能な薬液供給具であって、前記口部に接続可能で、かつ、前記容器内と前記容器外とを連通させる形状を有する基体と、前記基体に保持されており、かつ、前記容器内の閉塞及び被供給部への前記薬液の供給が可能な供給体と、を備え、前記基体は、当該基体からの前記供給体の離脱を阻止するように前記口部を基準として前記収容部と反対側から前記供給体に接触する抜止部と、前記容器内が閉塞されるように前記供給体を前記抜止部に向けて押し付ける押付部と、前記押付部の押付力に抗するように前記供給体が押圧されたときに当該供給体と当接することにより前記供給体の変位を規制する規制部と、を有し、前記供給体は、前記抜止部から離間することにより当該供給体と前記抜止部との間に前記薬液の前記容器外への供給流路を形成するとともに、前記抜止部と接触することにより前記供給流路を遮断する。 Further, the chemical solution supply device of the above embodiment can be connected to the mouth portion of a container which is connected to the accommodating portion capable of accommodating the chemical liquid and the accommodating portion and has a mouth portion which opens in a specific direction, and the mouth portion. It is a chemical liquid supply tool that can switch between a state in which the inside of the container is sealed and a state in which the chemical liquid in the storage portion can be supplied to the outside of the container in a state of being connected to the portion, and can be connected to the mouth portion. A substrate having a shape that allows the inside of the container and the outside of the container to communicate with each other, and a feeder that is held by the substrate and that can block the inside of the container and supply the chemical solution to the supplied portion. The base is provided with a retaining portion that comes into contact with the feeder from the side opposite to the accommodating portion with reference to the mouth portion so as to prevent the feeder from detaching from the base, and the inside of the container. The supply is provided by contacting a pressing portion that pushes the supply body toward the retaining portion so as to be closed and the supply body when the supply body is pressed against the pressing force of the pressing portion. It has a regulating portion that regulates the displacement of the body, and the feeder is separated from the retaining portion to provide a flow path for supplying the chemical solution to the outside of the container between the feeder and the retaining portion. At the same time as forming, the supply flow path is shut off by contacting with the retaining portion.

本薬液供給具は、容器の口部に接続されることにより、押付部の押付力に抗して供給体が押圧されたときに供給流路を通じて薬液が供給されるので、薬液の供給不足が回避され、さらに、供給体が規制部に当接することによって供給体の変位（押圧ストローク）が規制されるので、供給流路を通じた薬液の過剰供給が抑制される。よって、薬液の供給量を一定の範囲内に収めることが可能となる。
By connecting the chemical solution supply tool to the mouth of the container, the chemical solution is supplied through the supply flow path when the feeder is pressed against the pressing force of the pressing portion, so that the chemical solution supply is insufficient. This is avoided, and further, the displacement (pressing stroke) of the feeder is regulated by the feeder coming into contact with the regulating portion, so that the excessive supply of the chemical solution through the supply flow path is suppressed. Therefore, it is possible to keep the supply amount of the chemical solution within a certain range.
